    • Alternating Minimization for Wideband Multiuser IRS-Aided MIMO Systems Under Imperfect CSI 

      Pérez-Adán, Darian; Joham, Michael; Fresnedo, Óscar; González-Coma, José P.; Castedo, Luis; Utschick, Wolfgang (Institute of Electrical and Electronics Engineers, 2023-11-28)
      [Abstract]: This work focuses on wideband intelligent reflecting surface (IRS)-aided multiuser MIMO systems. One of the major challenges of this scenario is the joint design of the frequency-dependent base station (BS) ...

    • FDD Channel Estimation Via Covariance Estimation in Wideband Massive MIMO Systems 

      González-Coma, José P.; Suárez-Casal, Pedro; Castro-Castro, Paula-María; Castedo, Luis (M D P I AG, 2020-02-10)
      [Abstract] A method for channel estimation in wideband massive Multiple-Input Multiple-Output systems using hybrid digital analog architectures is developed. The proposed method is useful for Frequency-Division Duplex at ...

    • Hybrid Precoding With Time-Modulated Arrays for Mmwave MIMO Systems 

      González-Coma, José P.; Maneiro-Catoira, Roberto; Castedo, Luis (Institute of Electrical and Electronics Engineers, 2018)
      [Abstract]: We consider the utilization of time-modulated arrays (TMAs) as a simple and cost-effective approach to hybrid digital–analog precoding in millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems. ...
